'- GRAVITY GBAIN-SEPARATOR.

Specification tr Letters Patent. Patented Sept, 28, 1920.

r A'pplication filed August 2, 1919. Serial No. 314,994;

Toall whom it may concern Be it known that I, ANNA J. SOHLUNKE, a

citizen of the United States, residing at Fargo, in the county of Cassand State of North Dakota, have invented new and useful Improvements inGravity Grain-Separators, of which the following is a specification.

The object of my present invention is the provision of a grain separatorin which the operation is effected entirely by gravity, and which istherefore extremely simple and inexpensive in construction as well asdurable,

I the latter being largely due to the fact that it is unnecessary toincorporate movable parts in the separator.

To the attainment of the foregoing, the invention consists in thepeculiar and advantageous gravity grain separator hereinafter describedand definitely claimed.

In the drawings, accompanying and forming part of this specification:

Figure 1 is a longitudinal, vertical section of the separatorconstituting the best practical embodiment of my invention that I haveas yet devised.

Fig. 2 is a transverse section taken in the plane indicated by the line22 of Fig. I, looking toward the'left.

Similar numerals of reference designate corresponding parts in bothviews of the I drawings.

' Among other elements my novel separator comprises spaced and inclinedside frames 1. These side frames 1, together with a hopper 2 that isarranged to discharge in the space between the upper ends of the sideframes, are supported by a framework 3. I

In furtherance of my invention I arrange in inclined position betweenthe side frames 1, two chutes 4 and 5, the contiguous ends of which arespaced apart, as indicated by 6. Also in furtherance of my invention Iprovide the chute 4 at its lower end with a lip 7 while at the upper endof the chute 5 I provide a flange 8, the latter being of greater depththan the lip 7 in about the proportion illustrated. It will also beobserved that the contiguous ends of the straight portions of the chutes4 and 5 are arranged in substantially the same inclined plane.

By virtue of the described relative arrangement of the chutes 4 and 5,it will be observed that when grain is fed into the hopper 2, the samewill gravitate down the chute 4. The wheat units being smoother 'mentallower chute 5 King .scribed a supplemental chute 45 which is arrangedwith its upper portion opposite the space 6, and is provided at itslower end with an upturned lip 7 The scheme of my invention aselaborated is adapted to meet the condition that some of the wheat unitswill fail to jump across the space 6 and will fall with the oat unitsand the Kinghead units through the said space 6. Therefore I provide thesupplemental chute 4 The wheat units together with the oat and Kingheadunits will pass down the said chute 4 and then the operation beforedescribed will be repeatedi. 6., the wheat units will jump across to thechute 5, while the oat and Kinghead units will drop through the spacebetween the lip 7 and the flange 8, and will be discharged from theseparator on the chute 9 I u ould also have it understood that myseparator may be used to advantage in the separation of mustard seedfrom flax, and water grass and other weed seeds from hay seeds.

It will be apparent from the foregoing that notwithstanding itssimplicity and durability, my novel separator is expeditious andthorough in operation.

Having described my invention, what I claim and desire to secure byLetters-Patcut, is:

A grain separator comprising spaced frame sides, a hopper arranged todischarge grain between the upper portions of said frame sides, meanssupporting the frame sides and the, hopper, an upper inclined chutearranged to receive grain from the hopper and extending in inclinedposition downwardly between the frame sides and having an upwardlydirected lip at its lower end, a lower chute arranged in inclinedposition between the frame sides and with its upper end below and spacedfrom the lip at the lower end of the upper chute, a flange reachingupwardly from the upper end of "lower end, a reverseIy-inelined chute incom- 10 the lower chute, 'said flange-being of greater munication withthe Space between the lip depth than the lip of the upper chute, a ofthe fourth-named chute and the thirdchutezirranged between the framesides 'in -named'chute,iand an upstanding flange arpesition to receivegrain from the lower'ef fifnged between and commen to the thirdsaidchutes, 2L chute arranged between the- "named chute and the fifth-namedchute. 15 frame sldes 1n positlonto recelve gram from In tQStlIIlOIllX/whereof I affix Iny slgnature.
